Product Details

Starting with the massive Dirt Logic 4.0 Coilover Conversion, this system bolts directly in place of your factory coil springs, meaning you don't have to remove the coil spring bucket. The giant 4-inch diameter aluminum remote reservoir mounts horizontally above the coilover, giving you full compression travel even with oversized tires. This is Fabtech's biggest coilover for the Ford Super Duty, designed to handle serious off-road demands while still providing a comfortable ride on the street.

The heart of this system is Fabtech's tubular Radius Arms. Unlike the stock stamped arms, these are built with a tubular structure reinforced by a dimple die side plate and heavy gusseting, drawing design inspiration from Fabtech's race components. They feature an adjustable alignment cam at the axle for caster adjustment, offering a significant strength upgrade. This system also includes a Trac Bar relocation bracket, a Pitman arm, sway bar drops, and a rear block and U-bolt kit to complete the 8-inch lift.

This complete suspension upgrade is built to handle both on-road and off-road challenges, providing additional strength for use with oversized tires. Fabtech backs this system with a free 5-year, 60,000-mile powertrain warranty.
